Earthquakes
The vibrations in the ground that result from movement along breaks in Earth's lithosphere.
What is an earthquake?
Scientists who study earthquakes.
What is seismologists?
A vent in Earth's crust through which melted or molten rock flows.
What is a volcano?
Volcanoes that erupt very violently and explosively.
What are supervolcanoes?
The main chemical compound in all magmas.
What is silica?
What is a fault?
Instrument that that measures and records ground motion and can be used to determine the distance seismic waves travel.
What is a seismometer?
Molten rock below Earth's surface.
What is magma?
What are shield volcanoes.
Tiny particles of pulverized volcanic rock and glass are high into the atmosphere.
What is volcanic ash?
When a force such as pressure is applied to a rock along plate boundaries, the rock can change shape. This is called?
What is rock deformation?
A graphical illustration of seismic waves.
What is a seismogram?
Molten rock that erupts onto Earth's surface.
What is lava?
Large, steep-sided volcanoes that result from explosive eruptions of lava and ash along convergent plate boundaries.
What are composite volcanoes?
A liquids resistance to flow.
What is viscosity?
Energy that travels as vibrations on and in Earth. These are called what?
What are seismic waves?
A method that is used to find an earthquake's epicenter.
What is triangulation?
Volcanoes that are not associated with plate boundaries.
What is a hot spot?
Small, steep-sided volcanoes that erupt gas-rich, basaltic lavas.
What are cinder cones?
A seismic wave that causes particles in the ground to move up and down in a rolling motion.
What is surface waves?
What is the temperature, pressure, and chemistry of the rocks they travel through?
Magma forms when one plate sinks beneath another plate.
What is subduction?
A large volcanic depression formed when a volcano's summit collapsed or was blown away by explosive activity.
What is a caldera?
